Abstract: A system includes a first park circuit having a signal input, an output, and a control input. The system also includes a first signal path having an input and an output, wherein the input of the first signal path is coupled to the output of the first park circuit. The system also includes a second park circuit having a signal input, an output, and a control input, wherein the signal input of the second park circuit is coupled to the output of the first signal path. The system further includes a second signal path having an input and an output, wherein the input of the second signal path is coupled to the output of the second park circuit.

Abstract: A processor-based system employing a safety island architecture for fail-safe operation and related methods are disclosed. The processor-based system includes a main domain for controlling a device. The main domain receives and processes vehicle information from a vehicle network. The main domain communicates with vehicle modules to control operation of the vehicle. Such operation may include different autonomous driving use cases. The processing system includes a safety island domain that includes less hardware circuits as in the main domain. The safety island domain is configured to checkpoint vehicle information processed by both the main and safety island domains and to monitor errors originating in both the main and safety island.
